1. A brief history of anti-windup techniques
The term "windup" is historically related to the effect of actuator saturation in a control loop including an integral action , . In this case, when the input saturates, the integral term continues to load when it doesn't have to. The integrator output is then said to be in "windup". This unnecessary loading produces undesirable effects on the system's transient response, such as oscillations around the equilibrium point, or slow convergence...
